Kiths is a somewhat archaic term meaning "acquaintances" or "friends." If you're looking for other words that might convey a similar meaning, you could consider options like "mates," "buddies," "companions," "pals," "confidants," or "associates." Each of these words suggests some degree of personal connection, but they can also be used more broadly to refer to people you interact with on a regular basis. Depending on the context and the tone you're aiming for, you may also want to consider using words like "allies," "colleagues," or "contemporaries," which imply a more professional or intellectual connection.
